Growing vegetables the most headache is a variety of diseases and insect pests, once the occurrence of pests and diseases, many people obviously know that spraying is not good, but have to use pesticides for control, if not sprayed pesticides, vegetables may lead to a reduction in production or even harvest, which is no way for growers to do the way, today, to the farmers recommend a non-toxic, harmless, residue-free prevention and control of vegetable diseases methods, vegetables throughout the growth period only need to use 3 times, a season basically no disease, but also to increase vegetable production by 20%-60% , can be described as killing two birds with one stone.
Planting vegetables not only have technology, but also have experience, technology is learned, experience is accumulated, for the prevention and control of vegetable pests and diseases and increase production, the current fertilizers and drugs on the market can be said to be all kinds, everything, but most farmers are not willing to spray pesticides on vegetables, then today's sharing of this method can meet the needs of most farmers, it is chitnan, although chitosan is a drug, but this drug is not an ordinary pesticide, non-toxic, harmless, no residue, but also for food, The raw materials of health care products, you think, can such pesticides be harmful?
Chitosan is not a chemical synthesis, but by crabs and other marine organisms in the hard shell extracted from a substance, has been widely used in food, health care products, cosmetics, medicine, agriculture and other industries, in agriculture, a variety of crops of downy mildew, virus diseases, rot diseases, etc., have a good control effect, to vegetables after spraying, will form a protective film on the vegetables, bacteria and insect pests on the plant can not survive, known as plant protection vaccine.
Chitosan in vegetables and crops planting, is not limited to the control of pests and diseases, but also to promote the growth of plants, increase the yield of vegetables, in the cultivation of vegetables, you can use it to mix seeds, but also can spray and irrigate roots, and there is no resistance, after three years of use of chitosan, I summarized three particularly good formulas:
1, in the potato, sweet potato, garlic, ginger, radish and other root vegetables in the late growth, with 0.5% chibutan 60 grams, 60% chlorinated choline 15 grams, mixed with water 20 kg, spray on the front and back sides of the vegetable leaf surface, can effectively prevent the occurrence of various diseases, reduce drug costs, promote crop growth, but also significantly increase the expansion of tubers, roots, up to increase production of more than 50%, and there is no harm, chibutan and choline chloride are food-grade raw materials, safe and assured.
2. In the middle of the growth of cabbage, leeks, green onions, kale and other vegetables, with 0.5% chitosan 30 grams, potassium dihydrogen phosphate 25 grams, mixed with 20 kg of water, there is a good preventive effect on downy mildew, early and late blight, soft rot, etc., and can improve the cold resistance, drought resistance and flood resistance of crops, and the yield increased by about 30%.
3. During the growth of vegetables and other crops, if pests and diseases occur, they can be sprayed on both sides of the leaf with 300 times 0.5% chitosan at the beginning of the disease, with an interval of 3-5 days, and sprayed 3 times continuously. The interval between prophylaxis and prophylaxis is 7-10 days before onset. At the time of planting, it can also be sprayed with 100 times of chitosan solution on the seed to mix well, stay for 2 hours, and then sow, which has a good control effect on root diseases and soil-borne diseases, and can promote root system strength, significantly increase yield and quality.
I have used the above method many times, and it has proved that the effect is remarkable, and farmers may wish to try it.
If you want to know more about your experience and methods in planting, you are welcome to pay more attention to it.
